Lasers operating at the hundreds of terahertz range are used to cool, trap, and manipulate atoms in quantum simulation experiments. Drifts and fluctuations of the laser frequency can diminish the ...

Researchers used powerful XFELs to trigger strong inner-shell lasing, producing attosecond hard X-ray pulses. Filamentation and Rabi cycling helped explain these effects. Lasers, once confined to the ...

Model-Based Temperature Feedback Control of Laser Cladding Using High-Resolution Hyperspectral Imaging Laser cladding is a technique that is frequently used for the coating and repair of metallic ...
